Use Exchange Online PowerShell to delete a public folder
This example deletes the public folder Help Desk\Resolved. This command assumes that the Resolved public folder doesn't have any subfolders.
Remove-PublicFolder -Identity "\Help Desk\Resolved"
This example tests the previous command without making any modifications.
Remove-PublicFolder -Identity "\HelpDesk\Resolved" -WhatIf
This example removes the public folder Marketing and all its subfolders because the command runs recursively.
Remove-PublicFolder -Identity "\Marketing" -Recurse:$True
